I saw the Discovery Channel documentary on the Bismarck yesterday. It told about how bad the wheather was the day that all the Brittish ships moved in on the Bismarck, after it’s rudder got stuck. They started fireing on the Bismarck from 23 kilometres away, in very rough wheather. So that got me wondering, did the guns on those ships already have gyro’s to keep them level while the ship rocked on the waves?
From old footage I concluded that WWII tanks didn’t have them, so I always supposed that using a gyroscope for this purpose was a later invention.
If they didn’t have them on ships, how did they aim at a ship 23 KM away? And if they did use them on ships, how did they work, without computers? And in that case too: why didn’t they use them in tanks?
